Sigmoidoscopy

Sigmoidoscopy is a procedure to diagnose problems of the rectum and lower portion of the large intestine (sigmoid colon). It is accomplished by passing a colonoscope (a miniature camera on a thin, flexible tube) through the rectum and into the lower colon. In addition to seeing if there are problems, the doctor can use miniature tools to collect samples and treat some conditions (e.g. polyps).
